CAR-ROOF.

No. 913,412. Specification of Application filed April 13, 1907. Serial No. 367.946.

To all whom it may concern:

Be it known that I, JAM-Is Masnnn, a citizen of the United States, residing at llam- Inond, in the county of liake and State of Indiana, have invented a certain new and useful Improvement in Car-Roofs, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings; forming a part of this specification, and to the model filed herewith.

My invention relates to new and useful improvements in ear roofs of that class commonly known as inside roofs and particularl contemplates the provision of an inside roo constructed for the greater part of metal plates so held by the ridge ole and carlines that they are capable of in ependent movement to overcome theheavy strain put upon them, while at the same time forming an absolutely water-tight construction.

My invention further and specifically resides in the following features of construction and arrangement as will be hereinafter described with reference to the accompanyin drawings, forming a part of this specifica ion, in which like characters are used to designate like parts throughout the several figures, and in which,

Figure 1 is a perspective view of a portion of a roof constructed in invention, Fig. 2 is a similar view of one of the metal plates used therein, Figs. 3 and 3 1 l l are respectively a front elevation and a sec-l the fastening tional view of one of the securing elements, Figs. 4 and 5 are similar perspective views of intermediate and end carh es respectively,

Fig. 6 is a perspective view f the ridge pole,

Fig. 7 is a transverse sectional view through a portion of a completed car roof constructed in accordance with my invention, and Fig. 8 is a perspective view of one of the carline end caps.

n the practical embodiment of my 'invention and with particular reference to the drawings, 1 provide a ridge )ole A having longitudinal undercut channels A. and openings A therethrough communicating with said channels. C indicate a number of rec tangular metal plates having three of their sides formed with upstanding flanges C" having their longitudinal edges curled about metal rods C to strengthen the same, and having their abutting short edges soldered mgether.

mes B and B and B respectively are each l l tallie rod and adapted to be carried within l l accordance with my The intermediate and end earmg reduced ends fitting within said openmgs Patented Feb. 23, 1909.

' formed nith reduced ends l) adapted to lit snugly uithin the ol'icnings A in the ridge pole A. The intermediate carlines B are 1 further formed on the lower face with parallel channels 13'' while the end carlines B and B are provided on their lower face with 1 a single channel B, said channels B and B 1 being designed to receive loosely therein the longitudinal flanges (1 of the metal plates C arranged between the carlincs, the end flange (l of said plates being rovided with an angular extension ilange 9 raving an up uardly curled outer edge bent about a methe channels A of the rid e pole A, to form a closure for the upper en s of the carlines B thus forming with said plates, said carlines and said ridge pole a perfectly \vatertight structure while permitting the metal plates C sullieient play to prevent the buckling or bending of the same under the heavy tor- 1 sional strains imposed upon them. 1 In the car construction illustrated in Fig. 1 7, A represents the side thereof, B reprel sents the side beams secured thereto and F l represents the purlins, upon which the carlines rest. The straight edge of the metal plates C extends slightly beyond the sides A of the car and engages within slots D of bolted through the side securing plates D by bolts D Thus A and the side beam B the fastening of each element is provided for, securing plates D bolted through the side A and the side beam B by bolts 1). Thus of each element is provided for, the outer ends of the carlines being covered by caps E fitting thereover and bolted or otherwise secured to the sides A of the car. 5 From the foregoing description it will be seen that I provide a construction in which the main elements are securely, though movably held in their relative positions in such manner as to allow of suflicient movement I to prevent the buckling and bending of the l metal plates under the strain put upon them bv the pitching of the moving car and to allow the same to remain in their normal water-tight engagement.

Having thus escribed my invention, I claim:

In an inner car roof of the character deand having longitudinal channels therein, a of said carlines and said plates, substantially 10 plurality of metallic roof plates having upas described.

standing flanges on both sides and the upper In witness whereof I hereunto ailix my end thereof, said end flange havin an ansignature in presence of two witnesses this gular extension flange provided wit 1 an up- 8th day of April, 1907.
